Method and structure for lifting heavy punch of vibration molding machine

Abstract

The invention discloses a method and a structure for lifting the heavy punch of a vibration molding machine. When the heavy punch is put down by a lifting chain, the upper end of a heavy punch connecting shaft connected to the heavy punch is separated from the locating hole on a locating seat on an upper platform; after the heavy punch contacts a processed object, a spherical-surface bracket is continuously lowered to the position on which an upper spherical-surface seat is separated from a lower spherical-surface seat, wherein a spherical-surface analyzing cardo is formed by the upper spherical-surface seat and the lower spherical-surface seat, i.e. the top of the heavy punch connecting shaft connected to the heavy punch does not contact with the bottom surface of the upper platform of the vibration molding machine or any part on the upper platform of the vibration molding machine when the heavy punch is put on the processed object by the lifting chain for vibration processing; the upper spherical-surface seat and the lower spherical-surface seat of the spherical-surface analyzing cardo are mutually separated; and thus, the spherical-surface bracket and the lower spherical-surface seat do not contact with the heavy punch connecting shaft. The structure has the advantages of simple structure, low manufacture cost, good shock absorption effect, good practicality and the like, is convenient to install, is convenient to regulate and replace and is easy to maintain.

Description

technical field [0001] The invention relates to a weight lifting method and structure of a vibration forming machine, belonging to the technical field of vibration forming machines. Background technique [0002] At present, in the prior art, the weight lifting structure of the vibration forming machine generally adopts a long axis as a guide shaft extending from the upper platform on the vibration forming machine, and the lower end of the guide shaft is connected with the spherical dissection shaft that has been installed. In order to reduce the vibration of the upper platform during work, shock-absorbing rubber and spherical surfaces are designed on the connection structure between the guide shaft and the guide hole of the upper platform; the lifting of the heavy hammer depends on the lift installed on the upper platform The chain lifts. When this vibrating molding machine in the prior art is working, the weight is lowered and pressed on the material to be processed, and t...

AI Technical Summary

Problems solved by technology

When the vibration forming machine is working, the vibration source is transmitted to the guide shaft through the contact between the weight and the material, and then transmitted to the upper platform and the body of the vibration forming machine through the guide shaft. If the vibration isolation rubber is not installed and adjusted in place, it is very easy It is easy to cause unsatisfactory shock isolation effect; in addition, the existing heavy hammer lifting structure still has problems such as complex structure, high installation accuracy requirements, easy damage of shock isolation rubber, difficult replacement and maintenance, and poor shockproof effect of the upper platform. , so the effect of the existing hammer lifting structure of the vibration forming machine is still not ideal.
